TEFLARO CABP Study Designs1,4 | |
Type of trial: | Two randomized, multicenter, multinational, double-blind, noninferiority trials |
Study population: | 1231 adults with a diagnosis of CABP |
Comparative agents: | TEFLARO – 600 mg administered IV over 1 hour every 12 hours for 5-7 days; Ceftriaxone – 1 g ceftriaxone administered IV over 30 minutes every 24 hours for 5-7 days |
Adjunctive therapy: | CABP Trial 1, two doses on Day 1 of oral clarithromycin 500 mg every 12 hours; CABP Trial 2, no adjunctive macrolide therapy |
TEFLARO Study Populations | |
Day 4 Population* | |
MITT Microbiological Intent-to-treat | All subjects with a confirmed bacterial pathogen at baseline. |
EmMITT Exploratory Microbiological Modified Intent-to-treat | All randomized patients who received any study drug, had CAP that met radiographic criteria and had 1 or more symptoms at baseline, and had 1 or more acceptable baseline typical pathogens.7 |
Test of Cure (TOC) Populations† | |
MITT Modified Intent-to-treat | All randomized subjects who received any amount of study drug. |
MITTE Modified Intent-to-Treat Efficacy | All subjects in the MITT population who were in PORT Risk Class III or IV at baseline. |
CE Clinically Evaluable | All subjects in the MITTE population who demonstrated sufficient adherence to the protocol. Sufficient adherence is defined as patients who met the minimal disease criteria for CABP and for whom sufficient information regarding the CABP was available to determine the patient's outcome. |
ME Microbiologically Evaluable | All subjects in the CE population who had at least one typical bacterial pathogen identified at baseline from an appropriate microbiological specimen (eg, blood, sputum, or pleural fluid). |

To evaluate the treatment effect of ceftaroline, an analysis was conducted in CABP patients for whom the treatment effect of antibacterials may be supported by historical evidence. This analysis endpoint required subjects to meet sign and symptom criteria at Day 4 therapy: a responder had to both (a) be in stable condition according to consensus treatment guidelines, and (b) show improvement from baseline on at least one symptom of cough, dyspnea, pleuritic chest pain, or sputum production, while not worsening on any of these four symptoms.
The protocol-specified analyses included clinical cure rates at the TOC (8 to 15 days after the end of therapy) in the coprimary MITTE and CE populations and clinical cure rates at TOC by pathogen in the ME population.
